Switch statement help

[Drowningwater]

I'm writing a program and I've made a switch statement. I have several quesions:

1. I have a string variable and when I try to use that string variable with the switch function I get a compiling error that says: switch quantity not an integer
How to I get my switch statement to allow a string variable?

2. Can I make it accept 2 variables (i.e. If i wanted the person to type "go here" each word going into a seperate string variable)? ... maybe like this...

string hi, hi2;
...
switch(hi, hi2){
...etc.

3. Once inside the switch, how do I make a double word(like the ex. above, "go here") response?
ex:

switch(hi, hi2);{
case "go here": ...

-or-

switch(hi, hi2);{
case "go" "here": ...

or is it something completely different.


NOTE: I'm super new at C++ and I'm sorry if I'm not making a lot of sense, hopefully you'll get what I'm asking. Also since I'm new at this, please try to use basic C++ terminology that I would be able to understand.

Thank you.

Hi,

In C++, you can't pass a string variable to the switch statement.

You can pass only the integer variable.

Here is an example of using the switch statement.

 
#include <iostream.h>
 
#define  CHOICE_INCHES  1
#define  CHOICE_METERES 2
#define  CHOICE_QUIT    3
 
int main ()
{
   int
      nChoice = 0;
 
   do
   {  
      cout <<"Learn using switch case and do-while loop." << endl;
      cout <<"------------------------------------------" << endl;
      cout <<"\n1. Inches\n2. Meteres\n3. Exit\n";
      cout<<"\nPlease Enter the choices as shown above : ";
      cin >> nChoice;
 
      switch(nChoice)
      {
         case CHOICE_INCHES:
         {
            cout << "Inches\n\n";
            break;
         }
 
         case CHOICE_METERES:
         {
            cout << "Meters\n\n";
            break;
         }
 
         case CHOICE_QUIT:
         {            
            break;
         }
 
         default:
         {
            cout<< "Sorry, You have entered invalid choice.\n\n";
         }
 
      }
   }
   while(nChoice != CHOICE_QUIT);
 
   return 0;
}

Thanks. I think I've got a back up plan ;)

You could always take the first character of your first string and compare that. Characters can be represented as integers and, thus, can be used in switch statements.
